ALBERT HUGH STEVENSON, or LONDON, ENGLAND.

PAPER, CARDBOARD, AND LIKE RECEPTACLE OR CONTAINER.

Aippfication filed August 2,1921. Serial No. 489,330.

To all whom it may concern:

, Be it known that I, ALBERT HUGH S'rnvnN- soN, a subject of the King of Great Britam,

residing in London, England, have invented certain new and useful Improvements in and Relating toPaper, Cardboard, and like Receptacles or Containers, of which ,the'followingis a specification. v

This invention relates to receptacles or containers of the kind comprising a body portionof paper, cardboard, or like material having a metal bottom and a metal protecting or securing rim round the open mouth thereof. r

The object of the invention is to produce a receptacle of this kindin a more economical manner than heretofore.

According to the. invention, the body of the receptacle is tapered, or so formed that proportions between the" diameters of the mouth and the bottom are so arranged that the metal bottom and the metal rim forthe mouth-may be formed from a single metal sheet or disc, the sheet or disc being of such a size that it may be sta ped out into a central circular portion, orming the bottom of the container and a concentric annulus forming e rim thereof. These stamped out portions do not require any forming or shaping other than the usual rolling or bending in applying them to the receptacle. Preferably, the disc is stamped from a metal formin portionsin a'single operation, but

.obvious y the stamping may be carried out in a series of separate operations if desired. The metal bottom and the rim so formed may be applied to the body portion 'by any 40 of the known pressing and rolling methods usually employed.

To enable the invention to be fully understood it will now be described by reference to the accompanying drawing in which the application of the invention to a conical tubular container is illustrated:

Fig. 1 is an elevation of a conical tubular container with a metal bottom and rim formed according to the invention.

Fig. 2 is a plan view of a metal disc from which the metal bottom and rim. portions are formed and r Fig. 3 is a plan view of the disc after the stamping op ration, showing the separated portions whi h form the rim and bottom.

its mouth is wider than the bottom and the.

sheet and divided into the bottom and rim' Fig. 4 is a sectional view on line 4-4, Fig. 3, through the rim forming portion of the stamped blank and F ig.,5 is a similar view through the bottom forming portion of the stamped blank.

As shown, the containercomprises atapered body portion 1 of any suitable paperlike material such as paper, cardboard, fiber board, etc;, having a metal rim 2 and a metal bottom 3. The proportions between the mouth and bottom of the container 1 are so arranged that the metal portions for. forming the metal rim and bottom may be obtained-from a disc of metal 4 preferably without any waste.

The disc 4 is of such a size that when stamped as illustrated in Fig. 3, the central disc portion 5 forms the bottom of the container and the outer concentric annulus 6 remaining forms the rim. The-portions 6 and 5 are preferably of the cross sections illustrated in Figs. 4 and 5 respectively.

The bottom portion 5 is attachedto the bottom of the container 1 by inserting the dished portion 7 into the open bottom of the container and rolling or bending the flange 8 over the outside edge of the container in the known manner.

similarlyythe rim portion 6 is applied to the container by inserting the vertical portion 9into'the top of the container and rolling-or bending the flange portion.10 over the outside edge of the container in the known manner, the completed container having the appearance shown in Fig. 1.

Any suitable stamping apparatus and series of stamping operations may be used for forming the disc and the rim and bottom stampings and obviously these stampings may be of shapes other than those illustrated according to the type of rim and bottom it is desired to fit to the container. For-example,

the bottom need not be dished and the rim I sired portions, a ring of surplus material remains.

Further, the invention is applicable to containers of shapes other than conical or tapered, for example, the body .o f the container may be of spherical or outlived shape with top and bottom openings so proportioned as to allow the rim and bottom to be formed according to the invention.

Having thus described the nature of the said invention and the best means I know of carrying the same into practical eifect, I claim 1. A container comprising in combination a body portion of paper-like material, a

like body, consisting in stamping a metal disc into two concentric circular portions of such a size that the inner circle or disc forms the bottom without any further shaping other than securing it, and the outer concentric annulus forms the rim for the container month without any further shaping other than securing it. v

3. A container comprising in combination,

a body portion of paper-like material, a metal rim for one end, and a metal bottom for the other end, the metal rim. and bottom being formed by stamping two concentric from a single blank, the diameters of the ends of the body portion being so chosen that the rim fits one end and the bottom tits the other end.

5. The method of forming a container which consists in stamping a metal disk into two concentric portions one adapted to form a rim and the other adapted to form a bottom, and forming a body portion of paperlike material whose ends are of different diameter. the proportion between the diameters being such that the bottom fits one end and the rim fits the other end of the body, and

securing the rim and bottom to the ends of the body portion.

In testimony whereof I have signed my name to this specification.

ALBERT HUGH STEVENSON.
